MySQL Module is not working

I would like to use MySQL module with SSL certificate.
However, when I upload the certificate file from the options, I get the following error code.

error:0909006C:PEM routines:get_name:no start line


The options screen when entered from a file is shown below.

I believe this is due to the inability to break lines on the screen, is this not the case?

I would like to hear from anyone who has encountered similar events.
